A method and system provides for monitoring, troubleshooting and acquiring diagnostics information from an aspirating dispensing system (10). The dispensing system (10) uses an aspirator (12) with a plurality of liquid inlet ports and a flow meter (30) connected in liquid communication with at least one of the liquid inlet ports and a liquid source. The system monitors, troubleshoots and acquires diagnostics information from one or more components of the dispensing system by monitoring operation of the flow meter (30).

1. A method for monitoring operation of a dispensing system, comprising: providing a dispensing system having an aspirator with a plurality of liquid inlet ports and a flow meter connected in liquid communication with at least one of the liquid inlet ports and a liquid source;combining liquid product from the liquid source with a diluent from a diluent source at the aspirator;diagnostically assessing operation of one or more components of the dispensing system by monitoring operation of the flow meter;automatically switching the dispensing system from a flow-based dispensing mode to a time-based dispensing mode if one or more of the components of the dispensing system are determined to be inoperable or faulty; andproviding feedback based upon the assessed operation of the one or more components. 2. The method of claim l wherein monitoring operation of the flow meter comprises monitoring an output signal of the flow meter for assessing operation of one or more components of the dispensing system. 3. The method of claim 2 further comprising the step of storing the output signal from the flow meter in a data store. 4. The method of claim 3 further comprising the step of outputting the stored data for analyzing, troubleshooting or ascertaining historical information about the dispensing system. 5. The method of claim l further comprising the step of issuing a notification signal for apprising an operator or user of the operational status of one or more of the components of the dispensing system. 6. The method of claim 1 wherein the one or more components of the dispensing system comprise one of: a. a valve;b. a liquid product source;c. a flow meter;d. an aspirator;e. a control board;f. a liquid diluent source. 7. The method of claim 1 in combination with an on-site formulator. 8. A method for monitoring operation of a dispensing system, comprising: providing a dispensing system having: a. an aspirator with a diluent inlet port, a product inlet port and a use solution outlet port;b. a flow meter connected in liquid communication with the product inlet port and a liquid product source;combining liquid product from the liquid product source with a diluent. from a diluent source at the aspirator;diagnostically assessing operation of one or more components of the dispensing system by monitoring an output signal of the flow meter;automatically switching the dispensing system from a flow-based dispensing mode to a time-based dispensing mode if one or more of the dispensing system are determined to be inoperable or faulty; andproviding feedback based upon the assessed operation of the one or more components. 9. The method of claim 8 wherein diagnostically assessing operation of one or more components of the dispensing system comprises the step of determining a status of the liquid product source by detecting a change in the output signal. 10. The method of claim 8 wherein diagnostically assessing operation of one or more components of the dispensing system comprises the step of validating dispensing of a liquid product into the aspirator by monitoring the output signal. 11. The method of claim 8 wherein the dispensing system comprises a valve connected in liquid communication with the flow meter and the liquid product source. 12. The method of claim 11 wherein diagnostically assessing operation of one or more components of the dispensing system comprises the step of validating proper operation of the valve by monitoring the output signal. 13. The method of claim 8 wherein diagnostically assessing operation of one or more components of the dispensing system comprises the step of validating proper operation of the aspirator by monitoring the output signal. 14. The method of claim 8 wherein diagnostically assessing operation of one or more components of the dispensing system comprises the step of validating proper operation of the flow meter by monitoring the output signal. 15. The method of claim 8 further comprising the step of data logging the output signal for analyzing, troubleshooting or ascertaining historical information about the dispensing system. 16. The method of claim 8 in combination with a laundry system. 17. A diagnostics system for monitoring operation of one or more liquid dispensing components of a liquid dispenser, comprising: an aspirator with a plurality of liquid inlet ports and an outlet port for receiving two or more liquids and combining them therein;a flow meter connected in liquid communication to at least one of the liquid inlet ports and a liquid source, the flow meter having an output signal;a controller connected to receive the output signal of the flow meter to monitor and diagnostically assess operation of one or more liquid dispensing components of the dispenser;switching the dispensing system from a flow-based dispensing mode to a time-based dispensing mode if one or more of the components of the dispensing system are determined to be inoperable or faulty; andmeans for providing feedback based upon the output signal received by the controller. 18. The system of claim 17 wherein the one or more liquid dispensing components comprise a liquid product source connected in liquid communication with the flow meter, wherein the output signal of the flow meter provides an operational status of the liquid product source. 19. The system of claim 17 wherein the one or more liquid dispensing components comprise a valve connected in liquid communication with the flow meter, wherein the output signal of the flow meter provides an operational status of the valve. 20.
